Since the Obama administration altered the nation’s immigration enforcement policies in November with the president’s executive actions, Immigration and Customs Enforcement has released more than 600 detained immigrants from custody.

An ICE official explains to Breitbart News that, following Obama’s announcement, ICE instructed its field offices to ensure that the detention of those immigrants in custody remains in line with the updated enforcement priorities.

“That includes detainees who appear to qualify for Deferred Action for Childhood Arrivals (DACA) or Deferred Action for Parents of Americans and Legal Permanent Residents (DAPA), as well those individuals who, based on their case histories, no longer fall within DHS’ specified enforcement priorities,” the official said in a statement Breitbart News.

Those immigrants in custody who meet one or more of those apparent qualifications “are being released from ICE custody under an order of supervision pending a final determination in their cases.”

“Serious criminal offenders and other individuals who pose a significant threat to public safety remain a priority for ICE detention,” the official added.
